picking up from last week…
•Fire stair layout•Due October 18th
Assignment #1
Requirements
Use your studio project building dimensions Floor to floor heights Thickness of exterior walls and interior
partitions (they’re different) Use your design to calculate the
occupant load
Step 1: calculate occupant load
Step 2:Calculate dimension of egress components
•Plans, sections (2), and hidden elevation of center guard rail/hand rail•To scale•Fully dimensioned•Printed in black and white on 24x36” paper
Step 3: Design fire stair
other things to include
General project data: Use Group, Construction Type, codes in effect
Rize/run calculation Enlarged detail of the stair nosing Drawing indicating handrail mounting
and clearance

Fire Resistant Materials and Assemblies
Fire / Smoke Protection Systems
Passive systems: prevent fires Fire and smoke barriers Finishes and furniture
Active systems: once a fire has started Detection Extinguishing / Suppression Emergency lighting
Exiting systems: architectural elements Means of egress

“Compartmentation”
Passive fire protection means
The separation of areas in a building to control fire and smoke
Use Wall, Floor, and Ceiling Assemblies
“Fire resistance” (of assemblies) vs. “fire protection” (of penetrations in those assemblies)
“Fire barriers” (for compartmentation) vs. “fire and smoke partitions” (not specific to egress; residential, tenant spaces)
•All use standard materials•Sometimes in standard configurations
